For example, if window glass is likely to be broken by missiles during a windstorm, this is considered to be aastm opening. The missiles and their associated velocity ranges used in this test method are selected to reasonably represent ashm debris produced by windstorms. However, if doors and windows and their supports are designed to resist specified loads asrm the glass is protected by a screen or barrier, they need not be considered openings.

Wind pressures related to building design, wind intensity versus w1886, frequency of occurrence, and other factors are considered. Active view current version of standard. This test method is applicable to the design of entire fenestration or impact protection systems assemblies and their installation.

Other test methods, such as Test Sstm E and E, do not model gust loadings. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

When the windward wall of a building is breached, the internal pressure in the building increases, resulting in increased outward acting pressure on the other walls and the roof. Gust wind loads are of relatively short duration.

They are not to be specified for the purpose of testing the adequacy of the assembly to remain unbreached in a windstorm environment following impact by windborne debris. Thus, there are two options in designing buildings for windstorms with windborne debris: It is the responsibility of the user of this standard to establish appropriate safety and health practices and r1886 the applicability of regulatory limitations prior to use.

As demonstrated by windstorm damage investigations, windborne debris is present in hurricanes and has caused a significant amount of damage to building envelopes A missile propulsion device, an air pressure system, and a test chamber are used to model some conditions which may be representative of windborne debris and pressures in a windstorm environment.

Windstorm damage investigations have shown that the effects of windborne aatm, followed by the effects of repeated or cyclic wind loading, were a major factor in building damage The latter approach reduces the likelihood of asrm the building contents to the weather. The actual in-service performance of fenestration assemblies and impact protective systems in areas prone to severe windstorms is dependent on many factors.

adtm Design pressures based on wind speeds with a mean recurrence interval usually 25 to years that relates to desired levels of structural reliability and are appropriate for the type and importance of the building 1.

Note 1 — Exception: Certain values contained in reference documents cited herein may be stated in inch-pound units and must be converted by the user. Historical Version s – view previous versions of standard. Values given in parentheses are for information only. It is appropriate to test the strength of the assembly for a time duration representative of sustained winds and gusts in a windstorm.

Superimposed on the averaged winds are gusts whose aggregation, aztm short periods of time ranging from fractions of seconds to a few seconds may move at considerably higher speeds than the averaged winds. The performance determined by this test method relates to the ability of elements of the building envelope to remain unbreached during a windstorm.

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. A potentially more serious result is internal pressurization. Link to R1886 This link will always route to the current Active version of the standard.

The damage caused by windborne debris during windstorms goes beyond failure of building envelope components such as windows, doors, and curtain walls. This test method is applicable to the design of entire fenestration or impact protection systems assemblies and their installation. Specific hazard statements are given in Section 7.

However, these test methods do not account for other factors such as impact from windborne debris followed by fluctuating pressures associated with a severe windstorm environment.

The resistance of fenestration or impact protective systems assemblies to wind loading after impact depends upon product design, installation, load magnitude, duration, and repetition. Certain values contained in reference documents cited herein may be stated in inch-pound units and must be converted by the user. The performance determined by this test method relates to the ability of elements of the building envelope to remain unbreached during a windstorm.

This standard does not purport to address all of the safety concerns, if any, associated with its use. A missile propulsion device, an air pressure system, and a test chamber are used to model some conditions which may be representative of windborne ast, and pressures in a windstorm environment.

Typical debris in hurricanes consists of missiles including, but not limited to, roof gravel, roof tiles, signage, portions of damaged structures, framing lumber, roofing materials, and sheet metal 4, 7, 9. Breaching of the envelope exposes a building’s atm to the damaging effects of continued wind and rain 1,
